There is no way to type on docs editor. I create the new file and start typing and everything seems to go well but suddenly: POFF! No way to add a space and the characters appear as the following example:

I use a Lenovo Tab Plus tablet (Android 15) sometimes equipped with an external Silver HT keyboard.
I cannot write sentences as the characters appear in the following way:

This means: I start using the text editor and, after a few seconds, it is completely crazy.
I tried to repair it by updating (Only office and my tablet), uninstalling and reinstalling my external keyboard, deleting cookies, etc, but there is no way.

Can anybody help me, please?

Thank you very much in advance

Kind regards

Hello @FJPA

Category is set to Docs, but you have mentioned Android - do you use Docs in a browser or maybe Mobile app is being used? Please specify.

this thing happens to me when using the Android mobile app installed in my tablet.
Thank you for your reply

Can you provide a screen recording of this behavior and version of the Documents mobile app?

you can see in my first message
thank you for your interest in helping me

In your original post I see the samples, but can you record an actual behavior? Also, does this situation happen with both virtual and physical keyboards?
